Be it known that I, THAnnEUs A. JacksoN a citizen of the United States, residlng at Brooklyn, have invented a new and useful Improvement in Machines for Refinishing Metal 'Containers, of which the followlng is a specification. 1

This invention relates to machines for refinishing metal containers, the object being to provide .means whereby the operative elements employed to engage the side walls of a container with the planes thereof at right angles to the axis, may be ad usted to engage the bottom of the can with the planes thereof parallel with the said axis.

In short, the object of the lnventlon 1s to provide means whereby the same devices container, ma bottom of sal contamer.

employed to. refinish the side walls of a be adjusted to refinish the In the accompanying drawings, .Fig. 1 is a partial diagrammatlc elevation of my improved machine.

. 17, and

f slotted'block .19, and the'other end is conof spreader bars 28,

of the rock bars 25, so that Referrin to the drawings, 10 desi nates a table, slidably supporting a can older 11', whose long1tudinal movement is controlled 'by a hand wheel 12, pinion 13, and rack 14-.

A air of bearings 15 and 16 are fixed to a tab e 10, and support a tubular drive shaft a shift rod 18, which passes through said shaft 17 and carries at one end a nected to a shift lever 20, adapted to be locked against movement by a hinged rack shown. eyed to the shaft 17, is a head 23, having three slots 24, in which are arranged rock bars 25, hav'ng pivotal connection at the ends with link bars 26, which are pivoted to disks 27, carried at the outer ends pivoted in the slotted block 19. i v The circular heads 27-, have stub shafts 29, on which rollers 30, are rotatably mounted.

I provide a disk 31, slidable on shaft 17 and connected by rods 32, to the outer ends by manipulat- ,Kings County, New York,

ing a slide rack 33, over look teeth 34, the rolls 30, may be spread or adjusted to any desired distance or i 1 of the drawings.

power gear 35 is keyed to shaft 17 to rotate the .head 23, and in the operation of refinishing or smoothin out the walls of a metal container, one of which is shown at 35, in the holder 11, the link bars 26 engage the sides of slots 24, and take the torsional thrust as the rolls 30'operatively engage the inner walls of the container.

In the construction shown and described, it will be seen that the same rolls employed to engage. the side walls of the container are adjusted to engage the end wall thereof, and when in the latter adjusted position assume a position with their planes parallel with the axis of the container and-concentric with said axis so that no frictional drag can occur.

During the bottom refinishing operation the lever 20 is manipulated to feed the rolls radially inward and as the center is approached, the rolls may be, thrown to the opposite side of their swinging center by the rack 33, so that ractically the entire bottom may be refinis ied.

It is thought that the operation and utility of the machine will be ap arentwithout further description, and whi e in the drawings there is illustrated a preferred embodiment of the invention, it is to' be understood that the structural elements thereof are susceptible to such variations and modifications the scope of the appended claims.

What I claim is 1. In a machine of the class described, the combination with a holder f or a container,

of a plurality of rolls adapted to engage the.

sidewall of the container, means for adjustend wall of said container and means for driving the same, as described.

2. In a machine of the class described, the a holder for a container, of a. rotary. head, a plurality of annularly arranged rollscarried thereby and adapted to engage the side wall of said container, means for adjusting said rolls to engage the end wall of the container and means for driving the same as specified. 3. In a machine of the 'class described, in combination with a holder for a container,

angle, as shown in Fig.

- a revoluble head, rolls carried thereby and being adapted to engage the side wall of the container, means for adjusting said rolls to engage the end wall thereof, means for feeding the rolls in a radial direction during the a revoluble head having slots, a block slidable in said head, a plurality of disks having shafts, rolls carried on said shafts, links connecting the disks withthe head and bearing against the side walls of the slots, spreader bars connecting the disks with the combination with a holder for a container,

said block, means for causing the rolls to operatively engage the sidewall of the container, means for adjusting the said rolls to engage. the end wall thereof and means for driving the same, as described.

In testimony whereof, I have signed my name to this specification; this 31st day of July,-192O.
